Typing math

Hrmmm....  Idk....

 

 

By that theory... 

 

10 * (1/inf) * inf = 0?

 

(Parenthesis just for looks.)

 

10 * (0) * inf = 0.

 

Or:

 

10 * 1 / inf * inf

 

10 / inf * inf = 0

 

But....

 

1/x * x/1 always = 1, yes?  Or does infinity just break every rule?

 

 

 

(I should just read the wiki on infinity and stop arguing against things known to be true ;p.)

I'm pretty sure the way we were shown that 0.9999.. = 1 was something along the lines of:

 

let [tex]x = 0.\overline{999}[/tex]

 

then [tex]\frac{x}{10} = 0.0\overline{999}[/tex]

 

and [tex]x - \frac{x}{10} = 0.\overline{999} - 0.0\overline{999} = 0.9[/tex]

 

so [tex]\frac{9x}{10} = 0.9[/tex]

 

Therefore:

[tex] x = 1[/tex]

Or:

 

10 * 1 / inf * inf

 

10 / inf * inf = 0

 

The results of all that is undefined because you cannot multiply 0 with infinity.

 

 

I now hate infinity.

sorry

i mean

 

[tex]\[

\begin{array}{l}

S = 1 + 2 + 4 + 8 + 16 + 32 +  \ldots  \\

2S = 2\left( {1 + 2 + 4 + 8 + 16 +  \ldots } \right) = 2 + 4 + 8 + 16 + 32 \ldots  \\

S = 1 + 2S \\

S =  - 1 \\

\end{array}

\]

[/tex]

There is an editor called LyX which you can use if you don't feel like typing it in plain text. I believe they call it a WYSIWYM (what you see is what you mean) editor. I think it's available on all platforms. You can of course also just use vim and the CLI.

I occasionally get this meassage at the top of forum

 

No jsMath TeX fonts found -- using image fonts instead.

These may be slow and might not print well.

Use the jsMath control panel to get additional information.

If i would like to add this functionality to my app,

1.how do i go about installing?

2. Are the tutorials for this?

3. Could it be done on my localhost?

4. Could it be applied to a shared server without having to get the administrator to do it fer u?

 

I'm really a noob so i do apologise if i sound stupid...

Thanx guys...
